The Ardara coke works contain two batteries of block ovens and sit between Brush Creek and Route 993. These ovens were constructed in 1871 and were a sort of Carnegie experiment. He was attempting to make coke from a fine slack coal instead of the usual Connellsville coal. The demand for slack coal in steam engines closed these coke works in 1900.

| The cement blocks on these ovens were almost certainly added at later date. |
 |
| It would appear that the Brush Creek side of the ovens is prone to flooding more than the Route 993 side. |
